Disease relevance of Audiometry, Pure-Tone

• No subjects in either group showed hearing loss on pure tone audiometry, but otoadmittance abnormalities were recorded in 16 of the RA (42%) and in 2 of the control groups (7%) [1].
• MATERIAL AND METHODS: The DPOAE I/O functions at three F2 frequencies of 1001, 1501, and 2002 Hz were measured before and after the glycerol test following pure-tone audiometry for 16 ears of 16 patients with unilateral Ménière's disease [2].
• The present investigation was specifically designed to evaluate the ability of the glycerol test combined with pure-tone audiometry, distortion-product otoacoustic emissions (DPOAEs) to diagnose endolymphatic hydrops early and to identify patients who may evolve toward Meniere's disease [3].
• A controlled study of the reliability of pure tone audiometry for the detection of gentamicin auditory toxicity [4].
• CONCLUSIONS: A subgroup of patients with idiopathic sensorineural hearing loss (SNHL) will have steroid-dependent symptoms which can be confirmed using pure-tone audiometry [5].

Psychiatry related information on Audiometry, Pure-Tone

• While it appeared that a decrease in the negative SP after glycerol may be a more sensitive indicator of the changes within the cochlea than either pure-tone audiometry or speech discrimination, no clearcut correlations between this change and the surgical result could be demonstrated [6].
• Psychometric analyses of HCA, HQ, LOT, BDI, and GQL revealed high reliability in terms of Cronbach's Alpha and split-half r's. Significant intercorrelations were found between several measures, but not with pure-tone audiometry (0.5, 1, 2, and 3 kHz) [7].

High impact information on Audiometry, Pure-Tone

• On pure-tone audiometry, 19 patients were shown to have sensorineural hearing loss, 3 of whom had evidence of an added conductive element [8].
• Standard (0.25- to 8-kHz) and high-frequency (10- to 16-kHz) pure-tone audiometry was carried out in 70 CF patients, and the results were compared with the results from 91 control subjects [9].
• A self-report questionnaire on alcohol and nicotine consumption together with blood tests and pure tone audiometry were obtained for all subjects before the BAEP measurement [10].
• Pure tone audiometry and TMD data were obtained preoperatively ((0)) and postoperatively on day 1 ((1)) and 2 ((2)) [11].
• Hearing screening using standard pure-tone audiometry is recommended for cis-platinum patients as a routine procedure [12].

Biological context of Audiometry, Pure-Tone

• We studied microdosages of three selected enzymes--trypsin, alpha 1 antitrypsin, and alpha 2 macroglobulin--in each of the samples and their relationship with cochlear deterioration expressed in dBs of bone conduction decrease in pure-tone audiometry testing [13].
• The pure tone audiometry revealed sensorineural hearing loss with an average of 63 dB, and the auditory brain stem response demonstrated absence of all waves on the right side [14].

Anatomical context of Audiometry, Pure-Tone

• Auditory function was assessed by pure tone audiometry, auditory evoked brain stem responses (ABR), and transiently evoked otoacoustic emissions (TEOAE) to observe possible drug effect in the auditory system [15].
• The following methods were used: analysis of clinical evolution, pure-tone audiometry, determination of the immunophenotype of peripheral blood lymphocytes, immunoglobulins, complement factors C3 and C4, erythrocyte sedimentation rate, antinuclear autoantibodies (ANA) and heat shock protein 70 and the response to therapy [16].
• A total of 102 normal children underwent audiological assessment, including exclusion of middle ear disease, pure tone audiometry and DPOAE DP-grams (primaries L1/L2 = 65/55 dB SPL, f1:f2 = 1.22) [17].
• Her left tympanic membrane was slightly turbid and pure tone audiometry revealed mild left sensorineural deafness [18].
• In addition to ENG examinations and Békésy audiometry all patients were submitted to stapedius reflex tests and auditory brainstem response examinations (ABR) for signs of subclinical auditory nerve engagement [19].

Associations of Audiometry, Pure-Tone with chemical compounds

• Each patient underwent glycerol testing measured with conventional pure tone audiometry and with both DPOAEs [20].
• Pure-tone audiometry, transient evoked otoacoustic emissions (TEOAE), hearing in noise test (HINT) and gap detection were tested for each subject and compared to the serum aldosterone levels [21].
• Chloroquine gestational use in systemic lupus erythematosus: assessing the risk of child ototoxicity by pure tone audiometry [22].
• The SR test cannot replace pure-tone audiometry for the identification of cisplatin ototoxicity [23].
• The response to the furosemide test showed no relationship to the results of pure tone audiometry [24].

Gene context of Audiometry, Pure-Tone

• All the subjects were submitted to a pure tone audiometry, discrimination test, SISI test and TDT [25].
• The evaluation procedures were pure tone audiometry (PTA) and P300 cognitive potential [26].
• The hearing of 20 patients with idiopathic hypoparathyroidism was investigated by pure-tone audiometry [27].
• Normal-hearing (N:20) and sensorineural adults (N:15) performed sweep-frequency Bekesy audiometry from .1-8 kc/s at threshold and at MCL and UCL with both continuous (C) and interrupted (I) tones [28].
• Carefully screened normal-hearing young adults (5M, 25 F) performed a fixed-frequency version of high-frequency Bekesy audiometry (HFBA) with pure tones ranging from 2-16 kc/s, using the SHF E-800 unit (Gauz and Smith, J [29].

Analytical, diagnostic and therapeutic context of Audiometry, Pure-Tone

• As part of the test's evaluation process 172 patients with sensorineural hearing loss including 20 normally hearing subjects were measured using pure-tone audiometry, speech recognition threshold in noise (SRTN) test and conventional speech audiometry without background noise [30].
